No percentages: only things you can check.
This is not a one-time test
Every rating you give is already building your profile — your NDim ID. It lives and grows with you, and NDim Space uses it to find people who truly match you. A guest profile is kept for 7 days.
Why is there no compatibility percentage?
Percentages in online calculators are random. We show what you can check: your real matches — on the things you both rated.
Is it free?
Yes. No ads, no subscriptions, no purchases.
Will the second person see all my answers?
Only on the things of this test that you both rated — and only after each of you presses the button yourself. The rest of your profile is visible the way you decide.
